This book on "Analyzer and Report Generation Tool" is written with a view point of giving an exposure to the readers, for planning of large-scale simulation experiments, an efficient and flexible data collection and a statistically data analysis are important aspects to keep in mind. This tool allows a flexible and efficient data collection provides a software framework, which is fully integrated with NS2 that performs all the operations required to carry out simulation experiments in a statistically sound way. The framework allows a user to significantly reduce the post processing overhead and to save simulation time, especially with large-scale simulations.In my book a user is able to an integrated framework for network simulation easily, and the TCL scripts report generation and analyzer tool for statistical analysis of the simulated data with the ARGT (Analyzer and Report Generation Tool) for NS2 program.
